Abstract
The invention relates to a laying plank for a road finishing machine, comprising a basic plank (1) which exhibits two central upright cheeks (2), on which an extension cylinder (3) is arranged on each side which is guided by an inner cheek (8) of an extensible plank (4) for the lateral prolongation of the basic plank (1) and engages its outer cheek (5) for extending, at least one guide rods (7) parallel to the cylinder axis being provided respectively between inner and outer cheeks (5, 8), which is guided by an outer cheek (9) located on the basic plank (1). In order that the basic plank (1) can be enlarged virtually to double width by the extensible planks, it is provided that the cheek (9) located on the basic plank (1) is constructed as a sliding block slidable relative to the basic plank (1) along a guide means (13) connected to the latter, the extending cylinder (3) being connected to the sliding block (9 ) and slidable.
